hi everyone,

I'm beginning level for umbraco. I am trying to carry on a project that was already done and things are bad. I use umb // media / .. ads6a56fa5d6s .. to draw some pictures from another page. I read it elsewhere this solving:

// Your string which is retrieved from Archetype.
var imageString = "umb://media/c33bfe07a82b4df18a79db154139cb91";

// Get the guid from this string.
var imageGuidUdi = GuidUdi.Parse(imageString);

// Get the ID of the node!
var imageNodeId = ApplicationContext.Current.Services.EntityService.GetIdForKey(guidUdi.Guid, (UmbracoObjectTypes)Enum.Parse(typeof(UmbracoObjectTypes), guidUdi.EntityType, true));

// Finally, get the node.
var imageNode = Umbraco.TypedMedia(imageNodeId.Result);

But why am I getting an error for "guidUdi" here? How can I solve it.

Thank you
